Whats up everyone, I just bought a 325xi, and I had a question I figured one of you could answer. I just did a full tune up on my 325, oil, air filter, running 93 octane, and my car seems to have reaaaaaaallyyyyyy slow acceleration after 60 until about 80-90 then it picks up a little more. I have no mods in the car, fully stock. Very mint. Any suggestions on why this may be?

In the course of your "tune up" (whatever that means these days), did you maybe unplug something that didn`t get re-connected ?

What gear and what RPM range are we talking about here ?

 

[richierich325xi]

4th Gear, roughly 3k, I didnt unplug anything, I just changed an oil change, air filter change, and gave the car some TLC, but once im in 4th, the car is slow as a turtle.

You DO realize that you bought the slowest E46 in captivity, right ?

Is it stick, or auto ? Either way, try downshifting to third and *sting* it, running it up to redline before upshifting (which should put you at around 90 mph....)

I thought the 323 was the slowest of the e46? and its a Manual, it accelerates fairly quick from 0-60 and 90+ but that lull in between is sad, considering I've been passed by a ford focus.

FWIW, my lowly little E46 328 outpaced an E90 328xi recently. He had almost 40hp on me but it wasn't enough to overcome the drag of the AWD.

The AWD adds a couple hundred pounds and a lot of extra driveline friction, both of which suck the performance right out of that car.
Do what I said, downshift and use a lower, more agressive gear. BMWs thrive on high RPMs, and come to life in the top half of the rev band.

sounds almost like before I rebuild VANOS. Also putting some fresh gear oil into front/rear differential, MT fluid into gearbox and transfer case add some more life.
Use Redline or Royalpurple.

Thanks Fast Bob, I shifted around 4-5 and and in 4th around 5-6 and the car was hauling ass. And tonight the Focus got to watch tail lights slip away. Thanks very much Guys. :bigpimp:

OP, when you did your tune up did you replace spark plugs and your fuel filter?

 

[richierich325xi]

Everything, BUT the fuel filter.

My car pulls just fine in 4th from 3K to redline. There is a slight bump in power between 3.5 and 4.5k but you shouldn't feel any decline in thrust.

Also is your AC on?

Assuming he's got a manual transmission, this is actually not correct.

The slowest E46 is captivity is an AWD with a slushbox. Like mine.

So I guess that Crown is all yours, eh ? :bawling:

I will share the crown....

 

[Customisbetter]

The slowest e46 is the 325xi Auto TOURING.
